Answer:

B. NH₃ (l) dissolves in water to form a solution

Explanation:

A solution is a uniform or homogenous mixture of two or more substances. The components of a solution are the solute and solvent. The solute is the substance that is being dissolved in another substance. The solvent is the substance which dissolves the solute.

Mixing the given solutes in water results innthe following:

A. Helium being an inert gas does not dissolve in water at all. Therefore, no solution is formed.

B. Liquid ammonia is very solution in water. When mixed with water, it dissolves in water to form aqueous ammonia solution. Aqueous ammonia is an alkaline solution of ammonia dissolved in water.

C. Silicon (iv) oxide, SiO₂, is a crystalline solid whichnis completely insoluble in water. Mixing it with water does not result in the formation of a solution.

D. Pentane, C₅H₁₂, is a liquid hydrocarbon substance which is insoluble in water. It does not mix with water to form a solution, rather it forms two separate immiscible layers of liquids.

How is a nuclear weapon engineered?

Lady_Fox [76]

Answer:The first task of a nuclear weapon design is to rapidly assemble a supercritical mass of fissile uranium or plutonium. A supercritical mass is one in which the percentage of fission-produced neutrons captured by another fissile nucleus is large enough that each fission event, on average, causes more than one additional fission event. Once the critical mass is assembled, at maximum density, a burst of neutrons is supplied to start as many chain reactions as possible. Early weapons used a modulated neutron generator codenamed "Urchin" inside the pit containing polonium-210 and beryllium separated by a thin barrier. Implosion of the pit crushed the neutron generator, mixing the two metals, thereby allowing alpha particles from the polonium to interact with beryllium to produce free neutrons. In modern weapons, the neutron generator is a high-voltage vacuum tube containing a particle accelerator which bombards a deuterium/tritium-metal hydride target with deuterium and tritium ions. The resulting small-scale fusion produces neutrons at a protected location outside the physics package, from which they penetrate the pit. This method allows better control of the timing of chain reaction initiation.

What is the maximum concentration of Ag⁺ that can be added to a 0.00750 M solution of Na₂CO₃ before a precipitate will form? (Ks

Firlakuza [10]

Answer:

$\large \boxed{1.64\times 10^{-5}\text{ mol/L }}$

Explanation:

Ag₂CO₃(s) ⇌2Ag⁺(aq) + CO₃²⁻(aq); Ksp = 8.10 × 10⁻¹²

2x 0.007 50 + x

$K_{sp} =\text{[Ag$^{+}$]$^{2}$[CO$_{3}^{2-}$]} = (2x)^{2}\times 0.00750 = 8.10 \times 10^{-12}\\0.0300x^{2} = 8.10 \times 10^{-12}\\x^{2} = 2.70 \times 10^{-10}\\x = \sqrt{2.70 \times 10^{-10}} = \mathbf{1.64\times 10^{5}} \textbf{ mol/L}\\\text{The maximum concentration of Ag$^{+}$ is $\large \boxed{\mathbf{1.64\times 10^{-5}}\textbf{ mol/L }}$}$
